Description

Technical Field

[0001] The present application relates to the field of three-dimensional construction based on the Tekla platform, and more specifically to a steel grating modeling method based on the Tekla platform. Background Art

[0002] Steel grating is a kind of steel product with square grid in the middle, which is made of flat steel and cross bars arranged at a certain interval, and then welded by pressure welding machine or other welding methods. The upper surface of the cross bar is basically flush with the upper surface of the flat steel to ensure the safety and comfort of pedestrians. Steel grating is widely used in construction fields such as stair treads, walkways, work platforms, trestles, ditch covers, clean rooms, ventilation shafts, etc. due to its high strength, light weight, no water accumulation, good ventilation performance, strong anti-corrosion ability, easy installation, and flexible customization.

[0003] The flat steel of the steel grating is the load-bearing component. The crossbar is fixed on the flat steel to connect the load-bearing flat steel and stabilize the shape of the steel grating. At the same time, the upper surface of the crossbar and the flat steel is also the walking surface for pedestrians to pass safely. Therefore, the installation of the steel grating should take into account its actual use scenario. The flat steel must be firmly and firmly supported on the beam frame, and the walking surface of the steel grating should be facing upward so that pedestrians can pass safely on the walking surface.

[0004] The existing Tekla platform cannot easily create the actual form of the steel grating plate including flat steel and crossbars. The modeling work of the steel grating plate based on the Tekla platform usually uses the creation of solid flat plates to simulate the outline of the steel grating plate. In this way, the flat steel and crossbars of the steel grating plate cannot be reflected. This results in the inability to accurately identify the length direction of the flat steel of the steel grating plate and the walking surface of the steel grating plate in the 3D simulation model and its drawings.

[0005] To this end, the present application provides a steel grating modeling method based on the Tekla platform to at least partially solve the above problems. Summary of the invention

[0008] Establish a material library, which includes the corresponding steel grating plate model and unit volume weight;

According to the material library, the model of the steel grating plate used in the current steel grating plate and the corresponding unit volume weight are determined for the three-dimensional simulation model.

[0010] An outer surface of the three-dimensional simulation model perpendicular to the thickness direction of the three-dimensional simulation model is determined as a walking surface, and a mark is established on the walking surface. The mark represents the length direction of the flat steel, and the walking surface represents the upper surface of the steel grating.

[0011] According to the steel grating modeling method based on Tekla platform of the present application, the external dimensions of the steel grating, the length direction of the flat steel, and the walking surface of the steel grating can be determined through the established three-dimensional simulation model; the length direction of the cross bar can be determined according to the length direction of the flat steel; the relative positions of the cross bar and the flat steel can be determined according to the walking surface; the specification parameters of the flat steel and the cross bar can be determined according to the model assigned to the three-dimensional simulation model; in this way, the steel grating simulated by the three-dimensional simulation model can be accurately simulated.

[0028] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0029] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0030] Herein, ordinal numbers such as “first” and “second” cited in this application are merely identifications and do not have any other meanings, such as a specific order or the like.

[0031] In order to thoroughly understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also have other implementations.

[0032] The present application provides a steel grating modeling method based on the Tekla platform. The steel grating modeling method can establish a three-dimensional simulation model of the steel grating. After the three-dimensional simulation model is established, the external dimensions of the steel grating, the length direction of the flat steel, and the walking surface of the steel grating can be determined through the established three-dimensional simulation model; the length direction of the cross bar can be determined according to the length direction of the flat steel; the relative position of the cross bar and the flat steel can be determined according to the walking surface; the specification parameters of the flat steel and the cross bar can be determined according to the model assigned to the three-dimensional simulation model.

[0033] Please refer to Figure 1 The steel grating plate includes a flat steel 110 and a cross bar 120. The flat steel 110 is a rectangular parallelepiped structure. The cross bar 120 can be a cylindrical structure. The length direction of the flat steel 110 is perpendicular to the length direction of the cross bar 120. The cross bar 120 is located on one side of the width direction of the flat steel 110. The cross bar 120 connects one end of the flat steel 110 along the width direction of the flat steel 110. The steel grating plate is a rectangular parallelepiped structure. The length direction of the flat steel 110 is parallel to the length direction of the steel grating plate. The length direction of the cross bar 120 is parallel to the width direction of the steel grating plate. The width direction of the flat steel 110 is parallel to the thickness direction of the steel grating plate.

[0034] When the steel grating plate is in use, the width direction of the flat steel 110 is parallel to the vertical direction. The flat steel 110 is located below the cross bar 120. In other words, the cross bar 120 is located on the top surface of the flat steel 110. At this time, the upper edges of all the cross bars 120 away from the flat steel 110 are located within the walking surface 130 (the upper surface of the steel grating plate) of the steel grating plate. The walking surface is the pedestrian passage surface. The ends of all the flat steels 110 away from the cross bar 120 constitute the supporting surface 150 (the lower surface of the steel grating plate) of the steel grating plate. The supporting surface 150 and the walking surface 130 are arranged back to back. The steel grating plate is overlapped to the beam frame supporting the steel grating plate through the supporting surface 150 to be supported by the beam frame.

[0035] Please refer to Figure 2 The three-dimensional simulation model established by the steel grating plate modeling method is a solid plate model of a rectangular parallelepiped structure. The outer contour size (outer dimensions) of the solid plate model is the same as the outer contour size (outer dimensions) of the steel grating plate to be modeled. A mark 140 is set on one surface of the solid plate model. The direction indicated by the arrow of the mark 140 represents the length direction of the flat steel 110. The surface where the mark 140 is located represents the walking surface 130 of the steel grating plate.

[0036] The steel grating modeling method includes step S1, step S3 and step S5.

[0037] Step S1, establishing a material library, which includes the model and unit volume weight of the corresponding steel grating plate.

[0038] The material library contains various existing steel grating plate models and the unit volume weight corresponding to each steel grating plate model.

[0039] The model of the steel grating plate can be determined according to the model of the existing steel grating plate. According to the relevant standards of the steel grating plate, the specification parameters of the flat steel 110 and the cross bar 120 of the steel grating plate can be determined according to the model of the steel grating plate. The specification parameters of the flat steel 110 and the cross bar 120 include the specification and material of the flat steel 110, the specification and material of the cross bar 120, the spacing between adjacent cross bars 120, and the spacing between adjacent flat steels 110.

[0040] The unit volume weight of each type of steel grating can be predetermined according to the existing steel grating model. The unit of unit volume weight is kg / m3.

[0041] Step S3 is performed after step S1.

[0042] Step S3, establishing a three-dimensional simulation model simulating the outer dimensions of the steel grating plate, the three-dimensional simulation model is a plate-like structure, and determining the model of the steel grating plate used by the current steel grating plate and the corresponding unit volume weight for the three-dimensional simulation model according to the material library.

[0043] A three-dimensional simulation model simulating the external dimensions of the steel grating is established on the Tekla platform. The three-dimensional simulation model is a solid plate structure.

[0044] Among them, the cross-sectional shape of the steel grating plate whose cross section is perpendicular to the length direction of the flat steel 110 can be determined. The above cross-sectional shape is established in the Tekla platform, and the handle drawing direction is determined by connecting the two handles of the three-dimensional simulation model. The handle drawing direction is the length direction of the three-dimensional simulation model (the length direction of the three-dimensional simulation model is parallel to the direction indicated by the subsequent arrow, that is, parallel to the length direction of the flat steel 110), thereby completing the establishment of the three-dimensional simulation model.

[0045] According to the material library, the model of the steel grating plate used by the current steel grating plate (the steel grating plate to be simulated) and the corresponding unit volume weight are selected, and the selected steel grating plate model and the corresponding unit volume weight are assigned to the established three-dimensional simulation model.

[0046] Specifically, after the three-dimensional simulation model is established, the model of the steel grating is selected in the material library. At this time, the Tekla platform assigns the selected steel grating model and the corresponding unit volume weight to the three-dimensional simulation model as the model and unit volume weight of the three-dimensional simulation model. The weight of the three-dimensional simulation model can be determined based on the unit volume weight later.

[0047] Step S5 is executed after step S3.

[0048] Step S5, determine an outer surface of the three-dimensional simulation model perpendicular to the thickness direction of the three-dimensional simulation model as the walking surface 130, establish a mark 140 on the walking surface 130, the mark 140 represents the length direction of the flat steel 110, and the walking surface 130 represents the surface formed by the edge of the cross bar 120 away from the flat steel 110.

[0049] The outer surfaces of the three-dimensional simulation model perpendicular to the thickness direction of the three-dimensional simulation model are determined, and one of the outer surfaces is determined to be the walking surface 130 .

[0050] A sketch of the mark 140 is created on the walking surface 130, and the mark 140 is created by a polygonal cutting line command of the Tekla platform. The center of the sketch of the mark 140 can be the center of the walking surface 130. The walking surface 130 is a rectangle, and the center of the walking surface 130 is the intersection of the diagonal lines of the walking surface 130.

[0051] The mark 140 may be an arrow mark. The direction indicated by the arrow of the arrow mark indicates the length direction of the flat steel 110. It is understood that in an embodiment not shown, the mark 140 may also be other marks as long as it can indicate the length direction of the flat steel.

[0052] In this way, the walking surface 130 of the steel grating plate to be modeled can be determined by the plane where the mark 140 is located. The length direction of the flat steel 110 of the steel grating plate to be modeled can be determined by the mark 140.

[0053] In this way, the established three-dimensional simulation model can be used to determine the outer dimensions of the steel grating to be modeled, the length direction of the flat steel 110 of the steel grating to be modeled, and the walking surface 130 of the steel grating to be modeled; the length direction of the cross bar 120 can be determined according to the length direction of the flat steel 110; the relative positions of the cross bar 120 and the flat steel 110 can be determined according to the walking surface 130; the specification parameters of the flat steel 110 and the cross bar 120 can be determined according to the model assigned to the three-dimensional simulation model; in this way, the steel grating simulated by the three-dimensional simulation model can be accurately simulated.

[0054] The established three-dimensional simulation model can be used to determine the outer dimensions of the steel grating to be modeled, the length direction of the flat steel 110 of the steel grating to be modeled, and the walking surface 130 of the steel grating to be modeled. This can avoid incorrect installation of the flat steel in the length direction and the walking surface 130 when installing the steel grating, and avoid the flat steel being suspended in the air without being directly overlapped to the beam frame, thereby being unable to effectively bear the load and being damaged.

[0055] Optionally, the mark 140 is a notch formed by the walking surface 130 being recessed along the thickness direction of the three-dimensional simulation model toward the supporting surface 150 opposite to the walking surface 130. The width and depth of the notch are both small.

[0056] Optionally, the width of the mark 140 along the width direction of the three-dimensional simulation model ranges from 0.5 mm to 1.5 mm. Further, the width of the mark 140 is 1 mm. Thus, the mark 140 can be clearly displayed.

[0057] Optionally, the depth dimension of the mark 140 along the thickness direction of the three-dimensional simulation model ranges from 0.5 mm to 1.5 mm. Further, the depth dimension of the mark 140 is 1 mm. Thus, the mark 140 can be clearly displayed.

[0058] Optionally, a program (program file) of a parameterized node is established according to the shape of the mark 140. The program of the parameterized node includes the shape size of the mark 140, and the shape size of the mark 140 is stored as a constant in the program of the parameterized node.

[0059] The program of the parameterized node includes the position parameter of the marker 140. The marker 140 is bound to the upper surface of the three-dimensional simulation model, and the plane center of the marker 140 is made to coincide with the upper surface center of the three-dimensional simulation model.

[0060] The program of the parameterized node includes a direction parameter of the mark 140 so that the direction of the arrow of the mark 140 is consistent with the direction of the handle connection line of the three-dimensional simulation model.

[0061] In this way, the program of this parameterized node can be applied to the newly established three-dimensional simulation model, and the program of the parameterized node can automatically create a mark 140 with a uniform shape and size, and the direction of the arrow is consistent with the direction of the handle connection line of the three-dimensional simulation model at the center position of the walking surface 130 of the newly established three-dimensional simulation model. The size of the mark 140 established by the program of the parameterized node will not change with the size change of the newly established three-dimensional simulation model. The center of the mark 140 established by the program of the parameterized node always remains at the center position of the walking surface 130 of the three-dimensional simulation model (the intersection of the diagonal lines of the rectangular walking surface 130). In other words, the mark 140 established by the program of the parameterized node is centered in the length direction and the width direction of the walking surface 130 of the newly established three-dimensional simulation model.

[0062] Optionally, a new simulation model is established to simulate a new steel grating. The new three-dimensional simulation model can select the model of the steel grating in the database, and the Tekla platform will assign the model of the steel grating and the corresponding unit volume weight of the steel grating as parameters to the newly created three-dimensional simulation model. The walking surface 130 and the handle drawing direction of the new three-dimensional simulation model are determined. The handle drawing direction represents the length direction of the new three-dimensional simulation model, that is, the length direction of the flat steel.

[0063] A new mark 140 is established on the walking surface 130 of the new three-dimensional simulation model through a parameterized node program, so that the direction represented by the new mark 140 is the same as the handle drawing direction, and the handle line of the new mark 140 extends through the center of the walking surface 130 of the new three-dimensional simulation model and is perpendicular to the walking surface of the new three-dimensional simulation model.

[0064] Specifically, a parameterized node program is applied to the new three-dimensional simulation model, and a mark 140 with uniform shape and size and arrow direction consistent with the handle connection direction of the three-dimensional simulation model is automatically created at the center of the walking surface 130 of the new three-dimensional simulation model.

[0065] A handle of the parameterized node is set on the walking surface 130 of the new three-dimensional simulation model, so that a new mark 140 is established on the walking surface 130 of the new three-dimensional simulation model through the program of the parameterized node. The direction indicated by the new mark 140 is made the same as the drawing direction of the handle. In this way, the length direction of the flat steel 110 of the steel grating plate simulated by the newly established three-dimensional simulation model is the length direction of the newly established three-dimensional simulation model.

[0066] The handle line of the new mark 140 is extended through the center of the walking surface 130 and is perpendicular to the walking surface 130 of the new three-dimensional simulation model. The handle line is a line connecting two handles. In this way, the center line of the new mark 140 passes through the center of the walking surface 130 of the new three-dimensional simulation model, so that the new mark 140 can be created at the center position of the walking surface 130.

[0067] One handle of the new mark 140 coincides with the center of the walking surface 130, and another handle of the new mark 140 coincides with the center of the supporting surface 150. The supporting surface 150 is a rectangle, and the center of the supporting surface 150 is the intersection of the diagonal lines of the supporting surface 150.

[0068] In this way, a marker 140 of the same size can be quickly created in the newly created three-dimensional simulation model. The newly created marker 140 is located at the center of the walking surface 130. The direction indicated by the arrow of the newly created marker 140 is consistent with the direction of the handle connection line of the three-dimensional simulation model (that is, the handle drawing direction).

[0069] Optionally, the program storing the parameterized node is a format file. The format file is a specific format file. That is, the program of the parameterized node is exported and saved as (for example, saved to a computer hard disk) a format file with a specific format. Thus, the format file of the parameterized node can be used on Tekla platforms of different computers. In this way, the specific format file can be directly applied to a new engineering project.

[0070] Optionally, a node library is created that includes a program of parameterized nodes.

[0071] The format file of the parameterized node program can be stored in the node library on the computer hard disk. Subsequent new engineering projects can import the format file in the node library into the model and directly apply it to the modeling work of the new engineering project model.

[0072] The format file is included in the node library, and subsequent new engineering project models can directly import the format file from the node library for use.

[0073] Therefore, the required parameterized nodes can be selected through the node library, and the required parameterized nodes can be quickly established in the three-dimensional simulation model.

[0074] Optionally, the theoretical surface weight of the steel grating corresponding to the model of the steel grating is determined, and the unit volume weight is determined according to the theoretical surface weight of the steel grating and the thickness of the steel grating.

[0075] The unit of theoretical surface weight of steel grating is kg / m2. The theoretical surface weight of steel grating can be obtained by consulting relevant specifications and standards, and then the theoretical weight per unit volume of steel grating can be calculated by combining the thickness of the steel grating.

[0076] Optionally, the weight of the steel grating is determined based on the external dimensions and unit volume weight of the three-dimensional simulation model.

[0077] The volume of the 3D simulation model can be determined by the external dimensions of the 3D simulation model. The theoretical weight of the steel grating can be determined based on the volume and unit volume weight of the 3D simulation model. The above steps of determining the weight of the steel grating can be automatically completed by the Tekla platform. Thus, the weight of the steel grating can be easily determined.

[0078] Optionally, the engineering drawing is outputted through the three-dimensional simulation model, so that the engineering drawing can accurately represent the mark 140 of the steel grating plate simulated by the three-dimensional simulation model.

[0079] Engineering drawings can include information such as the model, dimensions, and walking surface markings of steel gratings. Steel grating manufacturers can prepare materials based on the model of steel gratings in the engineering drawings. The shape of the steel grating can be determined based on the dimensions in the engineering drawings. The walking surface of the steel grating and the length direction of the flat steel can be determined based on the walking surface markings in the engineering drawings.
